Any idea on how much weight you lost by using those rims?
I think the usual estimation is for every 1 lbs lost you gain about 10 HP from a rotating wheel, just curious if you weighed them for comparison?
They aren't MB wheels they are made by ACE. They are 1" wider than the OEM wheels, 18" front and rear. With the Hoosier competition tires the weight is 2.8 lbs less than OEM. The entire car is 368 lbs lighter than stock. I'm still working on reducing more weight.
I have always been told that reducing the weight of a car by 10 lbs is equivalent to adding 1 hp. Not sure about rotating mass.
